Good point, trimming trailing whitespace on save would really be helpful.

This is the standard text selection behavior on iOS—you can see the same in Apple’s Notes app, for example.

To place the cursor in the middle of a word, tap and hold the word to bring up the text loupe, which lets you position the insertion point precisely.

On iPhone, you can also tap and hold the space bar on the on-screen keyboard and then move your finger to move the insertion point more easily.

Thanks for your interest in Textastic for macOS. 

The macOS version and the iOS/iPadOS version of Textastic are two separate apps for two different platforms with different feature sets (the macOS version doesn't have remote connection support), so it would require two purchases if you want both.

Unfortunately, SMB connections in the Files app have been very unreliable for me in the past.

It works fine immediately after connecting to an SMB server, but as soon as it gets disconnected, it won't reconnect reliably. You need to recreate the SMB connection in the Files app and add it to Textastic again to make it work again when it is in this state. This is something out of my control that Apple has to fix.

I wouldn't recommend using SMB shares with the Files app. I have seen the problem you are describing as well as hangs when using the iOS Files app's built-in SMB client (not related to Textastic, reproducible in other apps like iA Writer).

Instead, I recommend to use Textastic's built-in SFTP client:

If you need live editing, I can recommend the app "Secure ShellFish" which allows you to connect to SFTP servers from the Files app and works great with the external folder feature of Textastic (the app's "Pro Unlock" is required for uploading changes):

Are you using an SMB connection in the Files app?

This is now fixed in Textastic 10.6.

I looked up previous user reports: for them, it happened when having multiple WebDAV connections to the same server URL, but with different user names and passwords.

Just to make sure: you are using different subdomains, right?

So one connection is to https://sub1.neocities.org/ and another is to https://sub2.neocities.org/

I think I heard a similar report from another user before.

I need to look into this more, but I believe the problem is that the WebDAV connections share the same session. So when you are connecting to the same domain, just a different subdomain, it will use the already established connection while it should actually try to authenticate again.

I don't have an environment like that to test at the moment, but I'll try to reproduce it.

Ok - it will be fixed in the next update. Thanks for letting me know!

It looks like iOS by default recognizes .as files as archive files, so Textastic thinks it's a binary file and shows it greyed out in file lists.

Please try to tap and hold the file and choose "Open as Text File" from the context menu of the file.

Does it work then?

I'll add .as to the list of known text files in an update.
